Try
<objective type="RandomPOIGoto">
<property name="phase" value="1" />
</objective>
for Challenge's, do not working for Quest's.
ex:
<!-- ChallengeTest -->

<property name="repeatable" value="true" />
<property name="icon" value="ui_game_symbol_zombie" />
<property name="category_key" value="challenge" />
<property name="difficulty" value="veryeasy" />
<property name="offer" value="ChallengeTest3" />
<property name="shareable" value="true" />
<property name="completiontype" value="TurnIn" />
<action type="TrackQuest" />
<!-- Phase 1 -->
<objective type="RandomPOIGoto">
<property name="phase" value="1" />
</objective>
<!-- Phase 2 -->
<objective type="RallyPoint">
<property name="start_mode" value="Create"/>
<property name="phase" value="2" />
</objective>
<!-- Phase 3 -->
<objective type="ZombieKill" id="zombieStripper" value="3" phase="3" />
<action type="SpawnEnemy" id="zombieStripper" value="5" phase="3" />
<!-- Phase 4 -->
<objective type="RandomPOIGoto">
<property name="phase" value="4" />
</objective>
<!-- Phase 5 -->
<objective type="ZombieKill" id="zombieStripper" value="5" phase="5" />
<action type="SpawnEnemy" id="zombieStripper" value="10" phase="5" />
<!-- Phase 6-->
<objective type="InteractWithNPC">
<property name="phase" value="6" />
</objective>
<reward type="Exp" value="5000" />
<reward type="Item" id="casinoCoin" value="5000" />
<reward type="SkillPoints" value="5" />
<reward type="LootItem" id="groupQuestMedical" ischosen="false" isfixed="true" value="5" />
</quest>
with:
<objective type="RandomGoto" value="500-750" phase="1">
<property name="completion_distance" value="50"/>
</objective>
you can change the value, go to whatever you want. "value=(minimum): 500 - (maximum): 750
